Your brain processes (visual) information at a resolution of >= 80ms[1]. The idea that you can tell the difference between 10ms or 50ms latency when typing is simply untrue (both events will appear instantaneous). I say this as someone that has played Counter-Strike professionally and have a sub-200ms reaction time. (Auditory perception is processed at a higher resolution, but the article is decidedly not about that.)

I almost noted on that as I've harped on sub-200ms for web responsiveness since the 90s.

However, reacting to something you see is a diff thing than sensing intra key-to-char lag in flow.

In CS, responding to what's on screen is diff from button press to seeing game action. High polling rate controls are going after that.

i cannot tell exactly but it kinda bothers me while working/typing

it is not like a huge latency, definitely not like ssh-connection.

to explain better, i usually have pre-defined set of keystrokes i input, so it's not the issue of latency of a single keystroke, rather compounding effect.

another thing is, most of the LSPs, highlighting etc are visibly slower on vscode. I am also having many plugins/extensions so that is partly to blame.

in the recent versions of vscode, they started supporting tree-sitter, which is quite nice in terms of performance.
